which portions of sheet metal are forced outj wardly by corresponding indenting on the opposite side.

4 4 represent the top and bottom bars `of the screen-section A, which are each formed from a strip of sheet metal folded centrally longitudinally upon itself and` inelosing the upper and lower marginal ortions of the wiregauze 1 and also partially inclosing the ends of the vertical bars 2 2, as indicated at 5 in Figs. 6 and 7'. The horizontal bars 4 4 are then provided with a longitudinal bead or beads 6 6, extending throughout' the length of the bars. In this form ofthe invention the lateral or vertical bars 2 2 are made slightly shorter than so that they will only project into the horizontal bars as far as the first bead 6, (see Figs. 6 and 7,) and the beads 3 3 do not extend throughout the length of the bars 2 2, but are stopped far enough from each end to clear the edges of the horizontal bars. The beads 33 serve only to hold the wire-netting in the frame-bars 2 2 land stifien the bars; but the beads 6 6 of the horizontal bars extend throughout the length of the bars and serve an additional purpose in that they assist in guiding the inner and outer screensections in their sliding movements, as hereinafter more fully explained, and l therefore term the bead or beads 6 6 of the horizontal frame-bars uiding-beads, to distinguish them from tlae beads on the vertical frame-bars.

It will be seen by reference to Figs. 3, 6,A and 7 and 7a that the horizontal and vertical bars of the inner screen-section are firmly united and held together bythe interlo'ekin of the wire gauze or nettin in the beade ortions thereof, and 'the wire-gauze `is also tightly stretched, sol that a sufficientlystrong and durable yet extremely light screen-section is formed Without the use of rivets r solder or other additional connection of the frame-bars. The dispensing with the use of rivets and solder further assists in reducing the cost of manufacture.. Y

The outer screen-section B(illustrated detached in Fig. 2 and in detail in Figs.`8 and 9) consists of a piece of wire gauze or netting provided with lateral `vertical frame-bars 8 8 ,made exactly like the corresponding'bars 2 2 of the other section and provided with a longitudinal bead lor b eads 9 9, (two beads being shown.) The upper and loweredges of the wire-gauze 7 are provided with horizontal frame-bars `10 10, which are each formed of a sheet of metal of greater width than the sheet used in making the corres onding bars 4 4 of the otherv section and olded longitudinally and jcentrally upon itself. The portion adjacent to the fold is'then bent over on one side, as shown in Fig.v 9 at 11, to form a retaining flange or uide, and the remaining portion is provide with 'a longitudihorizontal bars 4a bars are transversely therein by means of the -beads 6a 6.a, and this retaining-flan e 11c nal beador beads y12 12 on the face opposite to guide 11 and of such size that the groove or grooves 13 13, formed on the side adjacent to the retaining fiange or guide 1 1, will fit and guide the bead or beads, as in Fig. 7 at 6 6, of the inner screen-section. The topand bottoni parallel bars 10 10 of the outer screensection also embrace the end portions of the vertical bars 8 8, as indicated at 14, Figs. 8 and 9.

It will thus be seen that when the screensections A and B are constructed as before described the4 section A can be placed in eny gagement with the section B, the horizontal bars 4 4 of the inner section fitting within the guides or flanges 1 1 1 1 of the outer section and the guiding-beads 6 6 of the inner section .fitting and being guided in the grooves 1 3 y1 3 of the outer section, as shown in Figs. 1 4, and 5, thus enabling the screen to be extended laterally to fit any ordinarywindow-opening and forming a cheap, strong and light extensible screen.

In Figs. 10 and-11 I have shown a modification of the inner screen-section A in which the ends of the vertical bars (here designated 2a) are extended into the horizontal'bars 4f "f to the fold of the latter, and in beading the beaded and interlocked construction has certain advantages in the matter of the rigidity of the corners. It necessarily makes the screen thicker at these points than 'at intermediate points, and therefore the retaining-.flanges of the outside frames must be made to provide more room for,the inner frame.

Figs. 12 and 13 `are detail views showing the outer screen-section B also made in the manner just described, the ends of the vertical bars (here designated 8a) being extended the ends of the vertical TOO entirely within the horizontal bars 1()a and l locked therein by the beads 12a 12a, the retaining-flange 113L being constructed to accommodate the increased thickness of the inner section A at the corners, previously referred to with respect to Figs. 10 and 11.

In Figs. 14 to 19, inclusive, I have shown several modifications of the horizontal bars,

the` figures beingsectional views similar to Fi .5.

,n Fig. 14 the construction is exactly identical with Fig. 5, except thatthe retainingflange 11bo'f the horizontal bar 10b of the outer screen-section (here designated B2) is long enough to extend to the inner edgef of the frame and entirely inclose the frame-bar 4b of the inner screen A2.

In Fig. 15 the construction is identical with that shown in Fig. 5, except that the j of the horizontal bar 10c of the outer ame (here designated B3) is carried down the back of the horizontal bar 4c 'ofthe inner frame A3 below the Kfirst bead,

and said retaining-flange 11c is itself'beaded such case similarly v the provided with only a single bead.

f desired. In these figures the inner screenso as to fit into face of bar 4C. Y

In Fig. 16 the construction is the same as in Fig. 15, except that the retaining-ange (here designated 11d) is carried down over entire rear face of the inner yframe-bar 4d and is beaded to fit into both grooves, as shown.

In Fig. 17 a construction similar to Fig. 5 is shown, except that the bars 10e and `4e are `the outer groove on the rear Fig. 18 shows a that shown in Fig. 1 ing-flange 1 1f same width` as and 4f.

Fig. 19 is a view similar to Figs. 17 and 18, except that the retaining-flange 11.g is'of the same width as the frame-bars 10g and 4g and is also beaded to iit into the groove in the rear of the bar 4g.

In Figs. 20 to 23, inclusive I have` shown my improvements embodied in a screen construction similar to 7, except that the retainis straight, and it is of the the horizontal frame-bars 10f the screws 21 which is lnot-only laterally adjustable, but may be used as a vertically-sliding screen, if

section is indicated at A8 and the outer screen section at B8, said sections being constructed in this instance substantially in accordance with the construction illustrated in Fig. 17% that is, with a single bead and the top and bottom bars ,of the outer frame-section having the retaining-ilanges (here designated 11h) extending only a short way over the rear faces of said bars, as clearly shown in Fig. 21.

The outer side or vertical bar 2h of the inner screen-section and the outer side bar 8*' of the outer screen-section are each made of nearly double the width of the inner side barsand the portions thereof adjacent to the fold are bent rearwardly, as at 15 16, and are each beaded inwardly to form an exterior groove 17, (see Fi s. 20 and 21,) thus forming guiding grooved anges which project rearwardly from the outer ends of the screen and perpendicularly thereto. 18 18 represent vertical strips ometal each provided with a central outwardly-projecting bead 19., which are adapted to be secured to the guide-rails 20 of the window-casing by tacks or brads and form guides or runners for the guidingflanges 15l 16, as clearly shown in Fig. 20. These strips 18 18 are provided at suitable intervals with holes (not shown) through which the securing tacks or brads .may e driven to secure them to the window-casing. In Figs. 21 and 22 I have shownthe outer screen-section 'B8 having its top horizontal bar 10h provided with a screw 2 1-, passing therethrough and through a slot 22 in the in- I closed bar 4h of the other section. and pro- I vided on the rear side of the screen with a nut 23, andthe lower hbrizontal bars are in constructed. In fitting the window-casing so `that it l this screen to then screw up the screws.

21 21, whereupon the-screen is locked against lateral movement and may be raised and lowered and is permanently retained in the window-opening until removed by loosening In Fig. 23 I have illustrated a simpler means of fastening or locking the two frames B8 and A8 in their adjusted positions. In this construction the screws 21, slots 22, and nuts 23 are dispensed with, and after attaching the-strips 18 18 the/operator places the screen in the window and opens it until the ilanges 15-16 engage the strips, when he marks with a sharp instrument a scratch on the inner frame-bars 4h at the ends of the outer bars 10h, as indicated at 24, Fig. 23. The screen is then removed from the window, laid on a horizontal surface, 'and ex-l tended until 'in the same position which the screen sections occupied in the window, which will be'indicated by the scratches or marks 24. The operator then takes a pointed nail or other sharp instrument, such as a center-punch, and punches an indentation 9 in the overlapping portions of the horizontal frame-bars, as indicated at 25 in Fig. 23, thus indenting all the thicknesses of metal of the outer and inner frame at such points and securely locking the screen-sections together. The screen may then be replaced in engagement with strips 18 18 by sliding it down from the top, as isusual with a solid screen.

By means of the constructions shown in Figs. 20 to 23, inclusive, a purchaser of such extension-screen, or by attaching the strips 18 18 to the window-casing and adjusting and locking the screen-sections, as heretofore described, the screen may be quickly put in place and used as a permanent vertically-slidingy screen.
